Doing a Carb to TBI swap on my 77. Can I run the old style twist lock cap or do I need to change to a screw in style?

Assuming your referring to your fuel cap. If you keep the stock carb tank and run a frame mounted pump your going to have problems with the tank overpressurizing. Either find a vented cap or make sure your tank vent is clear of obstruction. I'd recommend doing both.

At least that was my experience.
 
Ooops.... Yea I am talking about fuel cap. Swaped to TBI tank/pump aready. But can't change filler cap yet. I kinda figured as long as tank had good vent I'd be ok.
